STA-5373 reported that #15927 dropped the `webContents.isDestroyed()` half of the guard #10065 added for STA-2373, and that the app therefore dies when a daemon death fans out to every pane. The guard is present on main: #15172 restored it at both senders when it split the PTY monolith, and a per-file count across v1.4.188..HEAD shows only relocation (pty.ts:4 -> write-input.ts:2 + bind-listeners.ts:2). The reported 4 -> 0 was scoped to `src/main/ipc/pty.ts`, now a 39-line barrel. No production fix is needed. What was real is that nothing pinned the guard — it survived #15927 only because #15172 happened to re-expand it — and the shared PTY test fake made that invisible: its `webContents` had no `isDestroyed` at all, so both guards passed vacuously in every suite. That is also why they are written defensively as `typeof ... === 'function' && ...`. - Give the fake an `isDestroyed` mock, re-stubbed to `false` each beforeEach rather than left `undefined`, so "alive" is stated rather than accidental. - Cover both senders red/green: the daemon-death fan-out (bind-listeners.ts:37) and the per-write reporter (write-input.ts:57). Verified red against a window-only guard and green with the real one. The per-write case needs a chunked write. A single-chunk write is already fenced by `isPtyWriteEventFromMainWindow`, which rejects the event once the WebContents is gone; only the multi-chunk path yields a macrotask mid-write, letting the renderer die after the sender check passes. That is the sole route to this sender with a dead WebContents, and what makes its own guard load-bearing. Also deletes `src/main/ipc/pty-renderer-surface.ts`: zero importers repo-wide, and its `isRendererGone` is exactly the weakened predicate. Its comment claims the headless path "now passes null", but register-headless-runtime.ts:26 still fakes `{ isDestroyed: () => true }` — #15172 rolled that back too. Adopting it would reintroduce STA-5373 for real. Verified: 17 tests across the two pty write suites; full src/main/ipc run 3156 pass (4 pre-existing @parcel/watcher failures in filesystem-watcher-real and worktree-base-directory-poller, unrelated and failing identically on a pristine tree); pnpm typecheck clean; oxlint clean.
